有吸湿性。100℃分解。溶于2.8份水、2份50℃的水，溶于碳酸钾溶液，不溶于乙醇。将水溶液煮沸则逸出二氧化碳而成为碳酸钾。0.1mol/L水溶液的pH为8.2。

碳酸氢钾是一种具有单斜晶体结构的水溶性碱性钾盐。它是合成许多钾化合物的原料。在气溶胶灭火装置中，它是比碳酸氢钠更好的冷却剂。它显示出作为抗真菌剂的潜力。

碳酸氢钾可作为合成碳酸二甲酯 (DMC) 的催化剂与环氧丙烷 (PO)、超临界 CO2(SC CO2) 和甲醇反应。也可作为亲核试剂在铱催化剂存在下合成支链烯丙基醇。

Potassium bicarbonate is water soluble alkaline potassium salt with monoclinic crystalline structure. It is a raw material for the synthesis of many potassium compounds. It is a better coolant than sodium bicarbonate in the aerosol fire extinguishing apparatus. It shows potential as an antifungal agent.

Potassium bicarbonate may be used as a catalyst in the synthesis of dimethyl carbonate (DMC) by reacting with propylene oxide (PO), supercritical CO2 (SC CO2) and methanol.It may also be used as a nucleophile for synthesizing branched allylic alcohols in the presence of iridium catalyst.
